Are the same as what? The front O2 sensor? The 92-98 sensor? What?

I just wanna know if that will fit my 02. It says it only fits 99 and 00.

There might have been some change to the size or shape of the cat converters after 00. Or they may not have thier converter certified for use on 01+ vehicles. Federal requirements are sometimes touchy about that, so even though it may fit, they aren't certified to sell it for that model year.

I'm also guessing that they don't think there will be anything wrong with a 3 yr old cat, which I think should be covered by the dealer warranty anyway. Why are you trying to replace it?

Warranty covers up to 80k miles. I have more miles than that. Looks like my flexpipe is leaking. If my local shop can't weld the leak, I would need a new one.

Then why are you trying to purchase a new catalytic converter? That link you sent me is for a converter, not a flex pipe. Huge difference in price BTW, converters are $150+, flex pipe should be a lot less. In any case, Flex pipes of the kind you are thinking can't be welded if there is a hole in them.

I don't think 99+ grandam's have a flex pipe anyway. I'm pretty sure all they have is a spring on the flange that flexes when the engine moves.

Why don't you take your car to an exhaust shop and get a repair quote that gives you an idea what needs to be fixed before asking if some random part that you may not need will work?

Well that is the whole thing, not just the cat. I thought the flex pipe is whatever is after that left flange? My flex pipe is leaking and I am taking my car to a shop. Thank you very much. I was asking just in case it's not fixable.

Ok, they said the flex pipe is broken and they can just order a new flange and a new flexpipe and just weld it on. $190 total. Not bad at all.
